Radiation-Pressure Enabled Traceable Laser Sources at High CW Powers

January 4, 2019
Author(s)
Paul A. Williams, Alexandra B. Artusio-Glimpse, Joshua A. Hadler, Daniel King, Ivan Ryger, Tam Vo, John H. Lehman, Kyle A. Rogers
Radiation pressure has recently been shown to have practical application for multi-kilowatt CW laser power measurement. One key advantage lies in its ability to measure without absorbing the laser beam. This enables a new measurement paradigm where laser

Defect Evolution of Ion-Exposed Single-Wall Carbon Nanotubes

January 3, 2019
Author(s)
Jana Kalbacova, Elias J. Garratt, Raul D. Rodriguez, Angela R. Hight Walker, Kevin A. Twedt, Jeffrey Fagan, Teresa I. Madeira, Jabez J. McClelland, Babak Nikoobakht, Dietrich R. Zahn
A systematic evaluation of defects is essential to understand and engineer device properties and applications. Raman spectroscopy is employed for the characterization of carbon nanomaterials in particular to quantitatively evaluate defects from the

Improving the Retrieval of XCO2 from Total Carbon Column Network Solar Spectra

January 3, 2019
Author(s)
Joseph Mendonca, Kimberly Strong, Debra Wunch, Geoffrey Toon, David Long, Joseph T. Hodges, Vincent T. Sironneau
High-resolution absorption spectra of the a^1 ∆_g←X^3 Σ_g^- O2 band measured using cavity ring-down spectroscopy were fitted using the Voigt and speed-dependent Voigt line shapes. We found that the speed-dependent Voigt line shape was better able to model

Towards quality assurance and quality control in untargeted metabolomics studies

January 3, 2019
Author(s)
Richard Beger, Warwick B. Dunn, Abbas Bandukwala, Bianca Bethan, David Broadhurst, Clary B. Clish, Surendra Dasari, Leslie Derr, Annie Evans, Steve Fischer, Thomas Flynn, Thomas Hartung, David Herrington, Richard Higashi, Ping-Ching Hsu, Christina Jones, Maureen Kachman, Helen Karuso, Gary Kruppa, Katrice Lippa, Padma Maruvada, Jonathan D. Mosley, Ionna Ntai, Clair O?Donovan, Mary Playdon, Daniel Raftery, Daniel Shaughnessy, Amanda Souza, Timothy Spaeder, Barbara Spalholz, Mukesh Verma, Tilman Walk, Ian Wilson, Daniel Bearden, Krista Zanetti
We describe here the agreed upon first development steps and priority objectives of a community engagement effort to address current challenges in quality assurance (QA) and quality control (QC) in untargeted metabolomic studies. This has included (1) a QA

Controlling femtosecond filament propagation using externally driven gas motion

January 2, 2019
Author(s)
Jared K. Wahlstrand, Nihal Jhajj, H M. Milchberg
The thermal density depression (or “density hole”) produced by a high repetition rate femtosecond filament in air acts as a negative lens, altering the propagation of the filament. We discuss the effects of externally driven gas motion on these density

Uncertainty Quantification of Failure Probability and a Dynamic Risk Analysis of Decision Making for Maintenance of Ageing Infrastructure

January 2, 2019
Author(s)
Jeffrey T. Fong, James J. Filliben, Nathanael A. Heckert, Dennis D. Leber, Paul A. Berkman, Robert E. Chapman
Risk, as the product of failure probability and failure consequence, has been estimated and applied by engineers and managers to help make critical decisions on (a) maintenance of ageing plants, and (b) planning of new infrastructure. For ageing plants

Artificial gauge fields with ultracold neutral atoms

January 1, 2019
Author(s)
Ian B. Spielman, Victor Galitski, Gediminas Juzeliunas
Gauge fields are ubiquitous in nature. In the context of quantum electrodynamics, you may be familiar with the photon, that represents the dynamical gauge field mediating electromagnetic forces. In fact all elementary interactions are mediated by gauge

Continuum of Quantum Fluctuations in a Three-Dimensional S = 1 Heisenberg Magnet

January 1, 2019
Author(s)
K. W. Plumb, Hitesh J. Changlani, A. Scheie, Shu Zhang, J. W. Krizan, Jose Rodriguez Rivera, Yiming Qiu, B. Winn, R. J. Cava, Collin L. Broholm
Spin liquids are a fundamentally new phase of matter that cannot be described by a broken symmetry and have no order parameter. While the quantum entanglement that characterizes a quantum spin liquid is not directly accessible to any current measurement

Efficient MU-MIMO Beamforming Protocol for IEEE 802.11ay WLANs

January 1, 2019
Author(s)
Munsuk Kim, Tanguy Ropitault, SuKyoung Lee, Nada T. Golmie
IEEE 802.11ay supports multi-user multiple-input-multiple-output (MU-MIMO). However, the MU- MIMO BFT (Beamforming Training) is a time-consuming process to find appropriate directional antenna patterns, and inefficient BFT results in a long training time

Enabling adoption of 2D-NMR for the higher order structure assessment of monoclonal antibody therapeutics

January 1, 2019
Author(s)
Robert G. Brinson, John P. Marino, Frank Delaglio, Luke W. Arbogast, Ryan M. Evans, Anthony J. Kearsley, Yves Aubin, Gregory Pierens, Xinying Jia, David Keizer, Jonas Stahle, Goran Widmalm, Chad Lawrence, Patrick Reardon, John Cort, Koichi Kato, Stuart Parnham, Andreas Blomgren, Torgny Rundlof, Kang Chen, David Keire, Thea Suter-Stahel, Gerhard Wider, Donna Baldisseri, Julie Wu, Mats Wikstrom, Medhi Mobli
Of the top ten drugs on the global market in 2016, seven of them are biologics with a combined market value of over US$60 billion. Moreover, around 2,800 biopharmaceuticals, many of them monoclonal antibodies (mAbs), are in some stage of clinical

Experimental Study of Fire-Induced-Delamination of Cross Laminated Timber

January 1, 2019
Author(s)
Daniel Brandon, Birgit Ostman, Joseph Su, Amanda Kimball, Matthew Hoehler
Cross Laminated Timber (CLT) is increasingly used as a structural material for tall buildings, due to its structural properties and low carbon footprint. CLT is a mass timber product, which is made by crosswise gluing layers of timber lamellae. Recent

Measurement of Ion-Pairing Interactions in Buffer Solutions with Microwave Microfluidics

January 1, 2019
Author(s)
Charles A. Little, Angela C. Stelson, Nathan D. Orloff, Christian J. Long, James C. Booth
Broadband microwave microfluidics is an emerging technique for quantifying the frequency dependent electrical response of fluids in the microwave regime. This technique can access important physical properties including interfacial polarization, ion
